tailings dewatering of mine and iron

Minerals Free Full-Text Dewatering of Mine Tailings ...

Traditional deposition of tailings slurry in a tailings storage facility (TSF) can create risks of dike failure. In order to minimize these risks and slurry spillage, the surface deposition technique of densified tailings (DT) through dewatering of the slurry has emerged. The DT technique has the potential to maximize water reuse, improve the shear strength of surface tailings, and reduce the ...

Minerals Special Issue : Dewatering of Fine Mineral

Based on the regulating behavior of Fe 3+, flocculation and sedimentation tests of iron tailings slurry flocculated using 2 mg/L anionic polyacrylamide (APAM) were studied, including the tests of Fe 3+ dosage, regulating time, and pH. Flocculation–sedimentation tests showed that: a recommended addition of 56 mg/L Fe 3+ produced a surprisingly bad flocculation effect; sedimentation ability ...
